Abstract
The utility model relates to a double-chain driving sower which comprises a machine frame, a seed dropping box, a land wheel, a chain driving system and a colter boot. The utility model is characterized in that the chain driving system has two sets of chain driving mechanisms, each of which comprises two action wheels arranged on a driving shaft of the land wheel, two driven pulleys arranged on a driving shaft of a seed dropping device, and a driving chain respectively arranged between the corresponding action wheel and the driven pulley. The double-chain driving sower is provided with two sets of chain driving mechanisms to obtain driving balance, when seeding is carried out after seeding rate is adjusted to a reasonable position, the driving shaft of the seed dropping device can not move right and left, and accurate seeding rate is ensured, and the consistency and the uniformity of the seeding rate are enhanced.
Description
Technical field:
The utility model relates to farm implements, the sower that a kind of and little four-wheel or the walking tractor matching of more specifically saying so used.
Background technology:
Existing sower is only installed a driving wheel on the ground wheel shaft, correspondence is provided with a driven pulley on the seeding unit power transmission shaft, and what constituted is one group of chain-drive mechanism.So, because the stressed effect of driven pulley causes the seeding unit power transmission shaft toward driven pulley end play is housed, cause sowing machine sowing amount inaccurate.
Summary of the invention:
Technical problem to be solved in the utility model is to avoid above-mentioned existing in prior technology weak point, and a kind of double-stranded driven type sower is provided, and makes the transmission balance, and the amount of broadcasting is accurate.
The technical scheme that the utility model technical solution problem is adopted is:
The utility model comprises frame, seeding box, land wheel, chain drive system and plough.
Architectural feature of the present utility model is that described chain drive system is two groups of chain-drive mechanisms, be included in two driving wheels that are provided with on the ground wheel shaft, two driven pulleys that on the seeding unit power transmission shaft, are provided with, and the driving chain that between each self-corresponding driving wheel and driven pulley, is provided with.
Can in two groups of chain-drive mechanisms, regulating wheel be set respectively.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
The utility model is provided with two groups of chain-drive mechanisms, reaches the transmission balance, and when sowing after the amount of broadcasting is adjusted to rational position, the seeding unit power transmission shaft left and right sides play can not take place, and guarantees that the amount of broadcasting is accurate, improves the uniformity and the uniformity of the amount of broadcasting.
Fig. 1 is the utility model master TV structure schematic diagram.
Fig. 2 is the utility model plan structure schematic diagram.
Fig. 3 is the utility model side-looking structural representation.
Embodiment:
Referring to Fig. 1, Fig. 2 and Fig. 3, seeding unit 7 passes through the positioning string of positioning sleeve 10 on seeding unit power transmission shaft 5, thereby be installed on the seeding casing 6, the adjusting device 23 of amount of seed metering is conventional version, specifically be installed on seeding unit power transmission shaft 5 and the seeding casing 6, seeding casing 6 is installed on the frame 20, land wheel 18 is installed on the ground wheel shaft 9 and by support 11 and is installed on the frame 20, plough 19 is fixed on the frame 20 by U-shaped silk 22, driving wheel 1 and driving wheel 15 are installed in respectively on the ground wheel shaft 9, driven pulley 4 and driven pulley 12 are installed in respectively on the seeding unit power transmission shaft 5, between driving wheel 1 and driven pulley 4, and between driving wheel 15 and driven pulley 12, install one respectively and hang driving chain 2 and driving chain 14, and carry out tensioning by regulating wheel 3 and regulating wheel 13, thus constitute two groups of chain-drive mechanisms.Broadcast amount adjusting apparatus 23 be mounted in two driven pulleys and seeding unit will not the optional position of shield on.
In concrete the enforcement, little four-wheel and pull bar 17 can draw walking by hanging articulating of pin 21, carry out seeding operation.
In the course of work, under little four-wheel traction, sower moves ahead, and drives land wheel 18 and rotates, rotation by ground wheel shaft 9, cause driving wheel 1 and driving wheel 15 to rotate,, drive driven pulley 4 and driven pulley 12 rotations by the engaged transmission of driving chain 2 and driving chain 14, thereby driving seeding unit power transmission shaft 5 rotates, cause seeding unit 7 to rotate and sow, seed enters in the ditch cave of being opened by plough 19 by funnel 8, seeding organ pipe 16, finishes sowing.
Claims (2)
1, double-stranded driven type sower, comprise frame, seeding box, land wheel, chain drive system and plough, it is characterized in that, described chain drive system is two groups of chain-drive mechanisms, be included in ground wheel shaft (9) and go up two driving wheels (1,15) of setting, go up two driven pulleys (4,12) that are provided with at seeding unit power transmission shaft (5), and the driving chain (2,14) that between each self-corresponding driving wheel (1,15) and driven pulley (4,12), is provided with.
